• Where to Fish on Thompson Lake

  Open data we checked carries no depth for this water. The old creek line under the surface is the feature worth finding. The arms fish better than the open middle whenever the water is up.

On Thompson Lake that means starting tight and working out.

• Seasonal Patterns

  Climate records put July near 70°F and January near 23°F. Winter closes the water for a while, and the reopening is worth catching. Look for the thaw near early April; the fishing lifts straight after. The lid tends to go about early April and return around late December. Late spring and early autumn carry the year between them. The season on Thompson Lake rarely departs from it.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. Parking sits half a mile out, which makes for a walk with tackle. Thorndike Reservoir Water Supply Land takes in this water; protected-area rules will apply. A small crankbait along the drop and a worm in the thick stuff cover the bass. A phone call first saves an afternoon. Signs go up and come down, so check on the day. The nearest alternative is Palmer Reservoir, 1 mile out. Rules at Thompson Lake are worth checking on the day.
